My ๐Ÿ‡ฉ๐Ÿ‡ช ๐Ÿš… diagram has been updated for 2026! It focuses on long-distance train lines that run at least three times a day. Providing a more interpretable alternative to 's official and diagram with a stronger focus on the system (regularly running connections and their frequency instead of the sole line definition) was my initial motivation for starting creating diagrams a couple of years ago.

Unofficial transport diagram of Germany. It shows the long-distance lines in an octolinear structure. Lines running on the same axes are coloured the same.
